Abstract

Composite diamond granules using granules of a ceramic substance line SiC as cores and covering the cores with a polycrystalline diamond coating are produced by the vapor phase method. The granules clearly manifest an automorphic diamond face and possess pyramidal projections, square faces, or rectangular faces on their surface. They are highly useful as abrasive granules for grinding. A grindstone obtained by mixing these granules with resin, metal, and vitrified binder and molding the resultant mixture is highly useful.
